Harvesting cancellous bone and marrow from distal femur, proximal tibia, distal tibia, or calcaneus using bone press apparatus

ABSTRACT

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

BACKGROUND OF THE INVENTION

The invention generally relates to methods and apparatus used forharvesting cancellous bone and marrow and, preferably, harvestingautologous cancellous bone and marrow from a distal femur, proximaltibia, distal tibia, or calcaneus of an individual for use as anautograft for that individual; and an intramedullary canal that isformed in a medullary cavity of a bone of an individual for use as anautograft for that individual, which bone of the medullar cavity may bethe tibia or the femur.

With regard to harvesting autologous bone, it is known when forming aintermedullary canal by reaming—which is basically done for a medullarynail—that autologous cancellous bone contained on the reamer afterwithdrawal may be recovered and used, if desired. Additionally withregard to specifically harvesting autologous cancellous bone and marrow,a procedure is known that is used for shallow-core harvesting ofcancellous bone and marrow from the posterior superior iliac spineimmediately prior to an anterior cervical discectomy/fusion (“ACDF”),wherein the harvested cancellous bone and marrow is used in thatindividual during the ACDF procedure. The procedure has been nicknamedthe “Ray Iliac Procedure” and is disclosed in U.S. Pat. Application62/868,779 and in 16/916,012, both of which are incorporated herein byreference. The Ray Iliac Procedure is intended for use in the orthopedicsurgical field.

The Ray Iliac Procedure is based on a repurposed use of a bone pressapparatus as disclosed, for example, in U.S. Pat. No. 8,920,393, whichis incorporated herein by reference. Such bone press apparatus arecommercially sold by Hensler Surgical Products, LLC, of Wilmington,North Carolina. The bone press apparatus was designed for harvestinghigh-speed drilled bone during spinal procedures, which harvested bonewas found to be a moldable and malleable matrix that could be reused inthe patient to increase fusion healing rates.

While the Ray Iliac Procedure is believed to be adequate for use inharvesting cancellous bone and marrow in conjunction with an ACDFprocedure, it is believed that additional improvements can be made inharvesting cancellous bone and bone marrow from other areas of the bodyby repurposing such bone press apparatus. Such additional improvementsare believed to be provided by one or more methods in accordance withone or more aspects and features of the invention, especially whenharvesting cancellous bone and bone marrow from condyles of the tibiaand femur and from the calcaneous, and when harvesting cancellous boneand bone marrow from an intermedullary canal formed in the tibia orfemur.

Indeed, it has been discovered that one or more methods in accordancewith one or more aspects and features of the invention result inunexpectedly high yields of cancellous bone and bone marrow, especiallywhen harvested from an intermedullary canal formed in the tibia orfemur; and unexpectedly high yield rates of cancellous bone and bonemarrow, especially when harvested from the condyles of the tibia andfemur and from the calcaneous, and from an intermedullary canal formedin the tibia or femur.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one havingordinary skill in the relevant art (“Ordinary Artisan”) that theinvention has broad utility and application. Furthermore, any embodimentdiscussed and identified as being “preferred” is considered to be partof a best mode contemplated for carrying out the invention. Otherembodiments also may be discussed for additional illustrative purposesin providing a full and enabling disclosure of the invention.Furthermore, an embodiment of the invention may incorporate only one ora plurality of the aspects of the invention disclosed herein; only oneor a plurality of the features disclosed herein; or combination thereof.As such, many embodiments are implicitly disclosed herein and fallwithin the scope of what is regarded as the invention.

Accordingly, while the invention is described herein in detail inrelation to one or more embodiments, it is to be understood that thisdisclosure is illustrative and exemplary of the invention and is mademerely for the purposes of providing a full and enabling disclosure ofthe invention. The detailed disclosure herein of one or more embodimentsis not intended, nor is to be construed, to limit the scope of patentprotection afforded the invention in any claim of a patent issuing herefrom, which scope is to be defined by the claims and the equivalentsthereof. It is not intended that the scope of patent protection affordedthe invention be defined by reading into any claim a limitation foundherein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps ofvarious processes or methods that are described herein are illustrativeand not restrictive. Accordingly, it should be understood that, althoughsteps of various processes or methods may be shown and described asbeing in a sequence or temporal order, the steps of any such processesor methods are not limited to being carried out in any particularsequence or order, absent an indication otherwise. Indeed, the steps insuch processes or methods generally may be carried out in variousdifferent sequences and orders while still falling within the scope ofthe invention. Accordingly, it is intended that the scope of patentprotection afforded the invention be defined by the issued claim(s)rather than the description set forth herein.

Additionally, it is important to note that each term used herein refersto that which the Ordinary Artisan would understand such term to meanbased on the contextual use of such term herein. To the extent that themeaning of a term used herein—as understood by the Ordinary Artisanbased on the contextual use of such term—differs in any way from anyparticular dictionary definition of such term, it is intended that themeaning of the term as understood by the Ordinary Artisan shouldprevail.

With regard solely to construction of any claim with respect to theUnited States, no claim element is to be interpreted under 35 U.S.C.112(f) unless the explicit phrase “means for” or “step for” is actuallyused in such claim element, whereupon this statutory provision isintended to and should apply in the interpretation of such claimelement. With regard to any method claim including a condition precedentstep, such method requires the condition precedent to be met and thestep to be performed at least once but not necessarily every time duringperformance of the claimed method.

Furthermore, it is important to note that, as used herein, “comprising”is open-ended insofar as that which follows such term is not exclusive.Additionally, “a” and “an” each generally denotes “at least one” butdoes not exclude a plurality unless the contextual use dictatesotherwise. Thus, reference to “a picnic basket having an apple” is thesame as “a picnic basket comprising an apple” and “a picnic basketincluding an apple”, each of which identically describes “a picnicbasket having at least one apple” as well as “a picnic basket havingapples”; the picnic basket further may contain one or more other itemsbeside an apple. In contrast, reference to “a picnic basket having asingle apple” describes “a picnic basket having only one apple”; thepicnic basket further may contain one or more other items beside anapple. In contrast, “a picnic basket consisting of an apple” has only asingle item contained therein, i.e., one apple; the picnic basketcontains no other item.

When used herein to join a list of items, “or” denotes “at least one ofthe items” but does not exclude a plurality of items of the list. Thus,reference to “a picnic basket having cheese or crackers” describes “apicnic basket having cheese without crackers”, “a picnic basket havingcrackers without cheese”, and “a picnic basket having both cheese andcrackers”; the picnic basket further may contain one or more other itemsbeside cheese and crackers.

When used herein to join a list of items, “and” denotes “all of theitems of the list”. Thus, reference to “a picnic basket having cheeseand crackers” describes “a picnic basket having cheese, wherein thepicnic basket further has crackers”, as well as describes “a picnicbasket having crackers, wherein the picnic basket further has cheese”;the picnic basket further may contain one or more other items besidecheese and crackers.

The phrase “at least one” followed by a list of items joined by “and”denotes an item of the list but does not require every item of the list.Thus, “at least one of an apple and an orange” encompasses the followingmutually exclusive scenarios: there is an apple but no orange; there isan orange but no apple; and there is both an apple and an orange. Inthese scenarios if there is an apple, there may be more than one apple,and if there is an orange, there may be more than one orange. Moreover,the phrase “one or more” followed by a list of items joined by “and” isthe equivalent of “at least one” followed by the list of items joined by“and”.

Referring now to the drawings, one or more preferred embodiments of theinvention are next described. The following description of one or morepreferred embodiments is merely exemplary in nature and is in no wayintended to limit the invention, its implementations, or uses.

Generally described, preferred methods of harvesting cancellous bone andbone marrow include extracting loosened cancellous bone and bonemarrow—including a liquid component thereof—to a collection containerthat has a first cup and a suction port to which a suction source isconnected. After suctioning, the suction source is disconnected and alid of the collection container is removed and replaced with a lidhaving a plunger with a press head that is configured to filter theextracted liquid by depressing the plunger toward a bottom of the firstcup. The filtered liquid is poured through a suction port into a secondcup while depressing the plunger, thereby separating the liquid from asemi-solid mass of cancellous bone that remains. The bone is extractedthrough a cortical opening in the femur, tibia, or calcaneus, andpreferably from a condyle; however, in other preferred methods the coneis extracted from an intermedullary canal that is formed by reaming ofthe tibia or femur using an orthopedic reamer.

Accordingly, FIG. 1 is a flow chart of an exemplary preferred method 100of harvesting cancellous bone and bone marrow in accordance with one ormore aspects and features of the invention. This preferred method isused to harvest such bone from the distal femur, proximal tibia, distaltibia, or calcaneous. The method 100 comprises steps 102 through 110.Step 102 comprises extracting loosened cancellous bone and bonemarrow—including a liquid component thereof—by suction to a collectioncontainer having a cup and a suction port to which a suction source isconnected. Step 104 comprises, after step 102, disconnecting the suctionsource from the suction port. Step 106 comprises replacing a lid ofcollection container with a lid having a plunger with a press head thatis configured to filter the extracted liquid by depressing the plungertoward a bottom of the cup. Step 108 comprises depressing the plungertoward the bottom of the cup to filter the extracted liquid. Step 110comprises pouring the filtered liquid from the first cup through asuction port into a second cup while depressing the plunger, therebyseparating the liquid from a semi-solid mass of cancellous bone thatremains in the first cup.

The suction port through which the liquid is poured in step 110 may bepart of the first cup or may be part of the lid having the plunger; inthe former case, the suction port to which the suction source isattached when performing step 102 is the suction port through which theliquid is poured in subsequent step 110, and in the latter case, thesuction port to which the suction source is attached when performingstep 102 is a suction port of the first lid, which first lid is replacedin step 106 by the second lid having the plunger. Moreover, it will beappreciated that the former case represents a modification to the cupdesign of the incorporated bone press apparatus, in which apparatus thecup itself does not include a suction port.

FIG. 2 is a flow chart of another preferred method 200 of harvestingcancellous bone and bone marrow in accordance with one or more aspectsand features of the invention. This preferred method is used to harvestsuch bone from an intermedullary canal formed in a medullary cavity. Themethod 200 comprises steps 202 through 214. Step 202 comprises creatingwithin a medullary cavity an intermedullary canal, including looseningfor extraction cancellous bone and bone marrow along the intermedullarycanal. Step 204 comprises inserting a suction tube through theintermedullary canal and extracting by suction through the suction tubethe loosened cancellous bone and bone marrow along the intermedullarycanal, wherein the bone marrow comprises a liquid, and wherein thesuction tube is attached to a lid of a collection container having a cupand a suction port to which a suction source is connected. Step 206comprises, after extracting the cancellous bone and bone marrow,disconnecting the suction source from the suction port. Step 208comprises removing the lid of the collection container from the cup ofthe collection container. Step 210 comprises attaching a second lid tothe cup of the collection container, the second lid having a plungerwith a press head that is configured to filter the extracted liquidcontained in the cup. Step 212 comprises filtering the extracted liquidby depressing the plunger of the second lid toward a bottom of the cup.Step 214 comprises pouring the filtered liquid from the cup through asuction port into another cup while depressing the plunger, therebyseparating the liquid from a spongy semi-solid cancellous bone mass thatremains in the cup.

The suction port through which the liquid is poured in step 214 may bepart of the first cup or may be part of the lid having the plunger; inthe former case, the suction port to which the suction source isattached when performing step 204 is the suction port through which theliquid is poured in subsequent step 214, and in the latter case, thesuction port to which the suction source is attached when performingstep 204 is a suction port of the first lid, which first lid is replacedin steps 208 and 210 by the second lid having the plunger. Moreover, itwill be appreciated that the former case represents a modification tothe cup design of the incorporated bone press apparatus, in whichapparatus the cup itself does not include a suction port.

FIG. 3 is a flow chart of another preferred method 300 of harvestingcancellous bone and bone marrow in accordance with one or more aspectsand features of the invention. This preferred method is used to harvestsuch bone from the distal femur, proximal tibia, distal tibia, orcalcaneous. The method 300 comprises steps 302 through 316. Step 302comprises creating an opening in cortical bone. The opening preferablyis made using a circular cutting burr, but other methods of creating anopening can in cortical bone may be used within the scope of theinvention, such as first drilling holes and then creating an openingwith a hammer and osteotome. One or more curettes also may be used tofurther expand the opening or round out the opening. Step 304 comprisesaccessing through the opening and loosening for extraction cancellousbone and bone marrow. Preferably the cutting burr also is used toperform such loosening.

As a result of the methods disclosed herein utilizing the bone pressapparatus with the suction for collecting both cancellous bone and bonemarrow and then separating the bone marrow from the cancellous boneusing the press head of the plunger, it has been discovered that anunexpectedly large yield of cancellous bone and bone marrow is obtainedfollowing intramedullary reaming. From actual implementation, 20 cc andmore of cancellous bone and 20 cc and more of bone marrow have beenobtained following traditional intramedullary reaming procedures used inconnection for an intramedullary nail or rod.

In recap of FIGS. 45-60 of the ‘911 Publication, preferred methods ofthe invention include harvesting cancellous bone and marrow from anintramedullary canal of an individual for use as an autograft for thatindividual following drilling and reaming. An exemplary method is nowset forth. In particular, a long pilot hole is created by a drill withinthe center of a long bone such as the tibia. Drilling and intramedullaryreaming loosens up the cancellous bone and marrow. Preferably, anintramedullary rod is inserted into the canal afterwards. Once depth ofdrilling to create the intramedullary canal is satisfactory for thesurgeon, the reamer is used. The reamer is cannulated whereby the guidewire remains within the canal the entire time. Multiple reamers are usedand set aside for keeping the bone to be added to the press later. Thebone captured on the reamers is scraped off with an instrument and usedin the autograft. Once the reaming is complete, the bone press apparatuswith suction is employed. A suction line is cut approximately 2-3 feetand attached to the silicon tubing. The tubing can be cut and the newsuction tubing can be placed over the superior port, but this is notnecessary, as the bone press apparatus preferably has a right angle forconnecting the tubes. With suction on, the cut suction line is insertedaround the guide wire. The guide wire does not leave the canal. Then bymoving the suction tubing all the way in and spinning the tubing inmultiple in and out motions within the canal and over the guide wire,cancellous bone and marrow is harvested from the medullary cavity alongthe intramedullary canal created by the intramedullary reaming. Oncedone, the collection is handed off to the scrub tech and the press topis attached. Of note, suction is not applied when the press head isused. Instead, the plunger is fully pressed downward and the apparatustilted to pour off the liquid marrow into a second container. Of note,suction is not applied when the press head is used. Instead, the plungeris fully pressed downward and the apparatus tilted to pour off theliquid marrow into a second container that is part of the bone pressapparatus.
